Drivers ahead of the truck who caused the crash were perfectly able to slow down and not crash, so forward vision was not an issue for them.
The driver who caused the crash simply wasn’t paying attention. It was his fault.

It's a bit more complicated than that. Cars use Hydraulic brakes, Trucks use pneumatically actuated systems. The Air systems adds a little more delay to the brake activation, this typically works out to about double the stopping distance for vehicles equipped with Air brakes compared to hydraulic systems. Sudden stops in a heavy vehicle can be very nerve racking as depending on how your load is arranged you can have the load trying to get in front of you (jacknife).

It’s not complicated at all.

One of the vehicles that this idiot crashed into was another semi with the same type of airbrakes that the crasher had. How come one truck was able to stop safely but the other one wasn’t?

Could it be that one driver was watching the road ahead and the other one wasn’t?
